One Love's First indoor grow - 2015

Hello Everybody!
I started my very first indoor grow four weeks ago.
Strain - 2 Pineapple Express x Blueberry (FEM, Auto), 1 Lowryder (Auto, Male)
Medium - vegetable soil with 20% Perlite
9L pots
250W hps in cool tube
One exhaust fan and one passive intake
Current temp is around 25C
Nutritions from Hesi
Closet size: 57cm*57cm*180cm (2'*2'*6')







My lowryder turned out to be male. I'm planning on pollinating one of my females.
Today I replaced my Jojo's with some strong wire because I heard they can break quite easily.
The soil have quite a bit fertelizer in it, so I have not been giving them any extra nutes yet.
They have been under the HPS for 2 days only

Last year I did my first outdoor grow, but in this area I'm very unexperienced, so every bit of advice is very appriciated. All I know, I've learned from forums, so I figured it's time to give some back. Hope you will enjoy!

An update and a problem

So when I startet this grow, I had alot more plants that I planed on using for my outdoor grow. Now I only have two left (decided not to pollinate). Problem is I might have mixed up my plants because something isn't right. What I should have is two Pineapple express x blueberry, Autoflowering, Feminized plants. What I do have are two different phenotypes. One with more sativa-looking leafs and on with more indica looking shorter and darker leafs and only the sativa-looking plant have shown sex.
I got these seeds from another grower. Could it be that these are a f1 cross between Pineapple express auto and Bluebery non-auto? I don't know alot about breeding but I have read about stable and unstable strains, wich could mean I could have one of each. How can I find that out?








The indica-looking plant (on the right) have alot darker color than shown in the pic.
On the up side, they are growing very fast and they recieved their first meal och nutritions today. Had some smell issues, but it's been taken care of.
